get to us, others pass us and turn into a neighborhood. still seeing helicopter overhead. it was down at one point, back up and still doing that orbit around this particular neighborhood. just a short while ago just before that press conference i spoke with the city manager. he talked to me about what they were doing to keep people in place. and also he said he wouldn't go into specifics of the investigation, but said it was far from over in this particular neighborhood in the watertown community because this is the last place they saw that suspect, was here. came down quite frankly where we are from cambridge into this particular neighborhood obviously throwing explosives out of the window. this is the last place they saw him. they believe he's here with all the people chasing him. with all the people, all the resources they had behind this person. they don't think he could have gotten far from here. so while there are other areas being cleared, there have been huge police presence in one area. we even saw military helicopters.

you can probably hear the helicopter in the air now. they're still zeroing in on watertown because they believe that is where this 19-year-old suspect is that we found out about. 19-year-old suspect who is a wrestler who got to college on a scholarship for wrestling. his older brother who is a boxer, a two-time golden glove champion both ending up in this neighborhood, one losing their life, the other on the loose still. again, you can hear that helicopter in the air. that is a police helicopter. also military helicopters here as well. and tactical units being disbursed throughout this area. so while they're clearing one area, as deb said, they cleared her area earlier. then they came back to the same area. that's what's happening here. far from over in this particular town. >> don lemon in watertown for us where the developments are unfolding rapidly. they're presumably, don, i want to be precise on this as well, they're presumably going

house-to-house, floor-by-floor with this search? it's a very dangerous operation given the potential for explosive devices to be located there. is that a good sense of what you're hearing and seeing? >> absolutely. and the pictures show it. we have seen it. i've seen it and the pictures show it as well. the bus loads and bus loads of police officers they have brought here, those were security people to watch the backs of the people who are actually going door-to-door. many times the s.w.a.t. team or tactical team would go door-to-door with their rifle, their assault rifle, military style rifles drawn, with their handguns drawn. they open the door, one would watch the other one's back and then they would all file in and go into a particular building. or they would knock on individuals homes. and what they were saying two individuals that that was going to happen. but before you open your door, make sure you knew that it was a police officer that you saw some sort of identification that they were dressed in police clothing. one scene that we saw earlier

this morning there was a s.w.a.t. team there. there was a k-9 unit there and also a chemist, wolf, on scene because they found blood at that particular scene and they were -- the chemist was taking samples to bring back to the lab so they can check to see if it matches blood from any of the other scenes and therefore they can figure out if that suspect was there or his whereabouts where he might be heading. >> a massive manhunt underway in the watertown area. chris -- don lemon is there. you know, chris, as we've watched this we're beginning to learn more and more about these two suspects, especially the younger one, the 19-year-old who's still on the loose. >> yeah. we heard from the uncle who gave us a really good background on where these guys grew up and the family. and very important to separate them from the family. say this is not about where we come from. it's not about our faith. these men are a disgrace. this is a shame. the suspect should turn himself in. very important in terms of as we

continue to pursue motivation here, it is just as likely at this point that these two men just decided to become crazed killer as it is that they're connected to any larger ideal. >> we're just learning more. chris lawrence is at the campus of the university of massachusetts in dartmouth where one of the suspects actually had been registered as a student at that school. campus is closed. there's a controlled evacuation underway. what else are you learning? what are some of his friends, associates, people who may have known him, what are they saying? >> wolf, there's been a lot of developments here on campus just in the last ten to 15 minutes. about 15 or 20 minutes ago we saw a helicopter land in the middle of the campus in an area that we don't have access to but we can see it flying over the trees and landing somewhere in the interior of the campus. right after that i saw about four to five police vehicles speed through the entrance of the campus going to that same

location. and then just within the last two to three minutes we saw two helicopters take off and leave the campus and head away. we also saw a big massachusetts state police tactical van arrive here very quickly, sort of an armored very large vehicle that just got on scene about five minutes ago. when i looked at the helicopters, again, they were in the distance. a lot of dust being kicked up. i didn't see any markings that indicates massachusetts state police so they may very well belong to the massachusetts national guard. also here we've been speaking with a lot of folks who knew dzhokhar. that's how they know him here, dzhokhar. in fact, we spoke with a young man who helped move dzhokhar in to his dorm when he first got to campus. and he was explaining to us how he was de-briefed by the state police and fbi this morning for about five hours.

he had tweeted out something when he saw some of our broadcasts and saw the picture, he tweeted out i think i may know this person, i think that's dzhokhar. and then this morning he got a knock on the door with police and investigators outside wanting to speak with him. they brought him to a nearby state police. they asked him if he communicated with people overseas, that was one of the questions he was asked. he said he couldn't remember that happening. and he had to explain to him what sort of person he was, what sort of interactions he may have had trying to give them any insight possible into the suspect they were looking for. wolf. >> chris, you're our pentagon correspondent. the way you describe it, it almost looks like a major military operation with sophisticated military equipment

in addition to local law enforceme enforcement. give us a few details of the military hardware you're seeing. >> right now so far it's been split. and i would say the majority of it is being the massachusetts state police, the local campus police are sort of doing perimeter security around the campus as they try to help students get off campus. a lot of students hanging out outside here trying to get a ride home or perhaps someone to pick them up. then we saw the helicopter off in the distance and we know just sort of trying to look through the buildings and the trees, i know it landed somewhere in the interior of the campus. and i know that the dorm -- dzhokhar's dorm is actually over on that other side of campus. i don't know if the helicopter landed near the dorm, but it was definitely on sort of the other side of campus from the entrance where we are and where a lot of

the students are coming out. then we saw that huge tactical vehicle from the massachusetts state police roll in after about four to five police cars came through. and then literally like i said just in the last ten minutes off in the distance we saw the two helicopters take off from the campus and fly away, wolf. >> pretty scary scene at the university of massachusetts in dartmouth. i'm sure it's the last thing, erin, that anyone would have thought on that campus that they were going to be seeing this kind of operation unfold on this day. >> yes. the shock they felt on m.i.t.'s campus as well last night when there was this shootout that happened. last night when we were standing here we had no idea there could be any link between these two things. and it has happened so quickly and unexplained. >> strange turns. and by no means over. >> no, not at all. erin observed earlier when we were here that most of the vehicles going by us were police and official vehicles.

you have to remember, this is one of the most extraordinary things we've ever seen in terms of terrorism work in the united states of america. this entire city, boston's one of the busiest cities in the world let alone in this country. and it's been shut down in a way systemically we've never done here before. and all because of this main question, where is this 19-year-old suspect who was involved in this hot pursuit? you have to say everyone we talked to agrees about one thing, the progress has been amazing. to think just monday this happened. >> so rapid, yeah. >> and they go through all this video, the possibilities, the permutations were almost endless. they come up with suspects, announce to the public and now here we are one suspect dead, the other one on the run. who could have imagined it would have taken this fast? not the experts. >> it's not over with yet. >> not even close, but to know who's involved, right, erin? >> that is incredible. you think it's going to be a needle in a haystack. >> once they got the pictures of the two suspects, they made it public, it was as a lot of law

enforcement types spoke to me it's only a matter of time somebody's going to recognize these two guys. we didn't know that they would allegedly go to a convenience store, rob it and then kill -- shoot and kill an m.i.t. security guard. >> significant work going. as you said, it's not over. they don't know if there are more people involved. that's why they're acting with such abundance. >> the amount of video, sometimes having too much is actually a bad thing. they were able to go through that so quickly and identify these two people. >> tom fuentes is joining us now as he has been over these past several days, former assistant director of the fbi, a cnn analyst right now. take us a little bit behind the scenes, tom. what's the biggest concern the investigators have right now even as they're closing in -- apparently closing in, we hope they're closing in, on the second suspect? >> well, i think, wolf, the biggest concern they have is that increasingly you have a cornered animal essentially.

he could get desperate. he could ambush the police officers that are searching apartment by apartment. he could set up booby traps and try to hurt or kill law enforcement officers by that means he could break into somebody's apartment, in other words do a home invasion and hold people hostage or become a barricaded subject with hazardous materials. so there's a number of possible problem situations that could develop in these last few minutes as they're trying to get him apprehended. as they close-in closer, he's going to become more dangerous. don't forget he's already dangerous. in addition to the marathon bombings that occurred last monday, he and his brother assassinated this m.i.t. police officer last night. that officer was not approaching them. he had nothing to do with any kind of suspicion of them apparently. he was sitting in his police car. and they ambushed him and murdered him. so they're the ones that began this attack last night. they're the ones that elevated

their profile between that attack and the armed robbery at the convenience store. and then the carjacking of another innocent person and shooting and throwing explosives, they're the ones that essentially went to war last night against law enforcement. there's still one member left, the younger brother, that can still continue that war right now. >> here's what i don't understand, tom. and i don't know if we'll ever understand this. they hijacked a car and the driver, take the driver hostage, they release the driver even after they basically boasted in the car that they were the guys who blew up the bombs at the boston marathon. that makes no sense to me. but maybe you have a better appreciation of the thinking of these kinds of guys. >> well, we talked from the beginning that they might have a mentality of wanting to gloat, you know, brag, take credit, feel glorified that they pulled this off. and it could be they just wanted

somebody to market that information for them to be able to go out and take that. similar to two months ago with dorner in california where after killing police officers and innocent citizens and chases and shootouts, he hijacks a car, you know, at that mountain top and lets that driver and his dog go and doesn't hurt them. so he invades a home and steals their car, but he doesn't hurt them either. it's hard to figure at what point somebody deems a threat. and in this case maybe he was, you know, for whatever reason did the carjacking, the two of them i mean, do the carjacking and didn't take it out on the driver. >> one of the suspects is dead, the other one remains on the loose. if they capture him alive, we might get some answers to these questions. if they find him and they kill him in the process of trying to capture him if he's a deadly threat, obviously we might never know the full story of what was

behind what was going on. >> which would be an awful thing. as we've talked about this is the first time an act like this has been pulled off successfully on u.s. soil. and given there are so many questions on the inspiration, the training, the relationship between the brothers, to not get answers would be a real blow to law enforcement and terrorism in this country. >> also an important message that the united states tries to send in situations like this is that they don't respond to violence with violence. so capturing him and putting him through the justice system is very important even optically to them. >> and we want to know and hopefully in the process of the questioning we might get some answers. three people were senselessly killed at the end of the boston marathon, nearly 200 people were injured. many of them remaining right now in critical condition. and now a security officer from m.i.t. killed for no reason. >> no reason at all. >> let's go to brooke baldwin. she's over there in cambridge where these two suspects, they lived there, brooke. and you were telling us they're getting ready for a controlled explosion because they fear they may have found some more

explosives. >> yeah, that's precisely right, wolf. we're going to stay on these live pictures. i'm standing just off camera watching all after this unfold in front of my eyes. so what you see is the yellow crime scene tape and about half a dozen firefighters here. you see some of those agents moving in. those are fbi agents with the fbi vests in walking in. we're in watch and wait mode. we learned about the controlled explosion at that news conference just about an hour ago. and we have not really seen any hustle, any major activity other than everyone sort of just standing by. but where you see that tape, that is norfolk street. so if you hook a right and you go past those firefighters and down that street just about a football field and a half away, that is that apartment complex where these two young men had lived. what you can't see in this shot but i can set the scene for you, i am staring at an american red cross disaster relief truck. there are one, two, three ambulances here on standby.

i've seen state police. i've seen cambridge police. somerville police, somerville is a neighborhood just around the corner from us here in cambridge. so we are awaiting these controlled explosions. and any case like this of course you have to think five steps ahead if you're law enforcement. and if this is where these two men lived and if in fact they were the ones capable of monday's horrendous, horrendous bombing, who knows what's inside of that apartment. so they have to take every precaution to make sure it's safe before they can go in and search it, wolf. >> how close are you, brooke, to what's going on over there? media are relatively far away for understandable reason. >> yeah, you know, i've been here all morning long. so i'm staring with my own eyes at these firefighters you're looking at i would say they're maybe i don't know 100 to 150 feet right in front of me, 12:00. and i was earlier this morning just across the street from them

much, much closer. but there was a point when a lot of the fbi agents rushed toward the media. and i got to tell you it's a crush of media here as you can imagine several dozen outlets out here, reporters, photographers. so they suddenly said you have to move, you have to move. a cambridge police officer walked toward me and said it isn't safe. so slowly but surely and see deborah feyerick and her situation in watertown today, we have slowly had to creep farther and farther back. i have to mention too, wolf, not just members of the media out here but folks who live along norfolk street. i saw a mother changing her baby's diaper on the sidewalk because they're stuck. they have nowhere to go because of these controlled explosions. they have to sit and wait just like the rest of us, out of precaution, wolf. >> apparently a lot of explosive devices in the area. right now law enforcement working. brooke, we'll get back to you. you know, erin, as we watch what's going on, we're here in

boston. it's a pretty nerve racking situation. >> it is a nerve racking situation and they do believe the suspect's armed and dangerous and there could have been pipe bombs left around which creates a real sense of fear. >> which is why they're doing these controlled explosions. just to be precise what that means is experts go in there and detonate these bombs to make sure they don't kill anyone. >> that's right. they want to make sure there are no other casualties in the horror that's gone on the past few days. we're going to take a quick break. we'll be back with the live coverage of the breaking news manhunt here in boston. ♪ [ jen garner ] what skincare brand is so effective...

welcome back. authorities in the boston marathon bombing investigation plan to conduct controlled explosions later today in cambridge. we've been talking a bit about these, but we want to make sure you understand what they're doing. they made this announcement a short time ago which seems to indicate as wolf was saying before the commercial break that they found more explosives tied to the defective bombers. they want to detonate them in a controlled way so they no longer pose a threat to public safety. one suspect is dead. one is still on the run. here's the very latest we know right now. authorities have identified the boston marathon bombers as brothers, tamerlan and dzhokhar tsarnaev. they are from a predominantly muslim region in russia. the 19-year-old brother believed to be extremely dangerous possibly armed with explosives on his person. unclear whether he was injured in the shoot outlast night in

which his 26-year-old brother died. it's unclear whether he's injured and hiding somewhere and unable to move, whether he moved, they don't know right now. we're told that the brother was wearing explosives and a triggering device when he died which is why they're worried -- >> the older brother. >> the older brother. this is why they're worried the younger brother could be in a similar situation. this happened overnight and intensified. police say the suspects robbed a convenience store, shot and killed an m.i.t. police officer. i was on the air live when that happened last night, wolf. and as you know, it was no expectation at that time that there was any relation between the two things. but there ended up being. >> and when they heard of a convenience store robbery, stuff like that happens. >> right. >> some security guard from m.i.t. was shot, people didn't put that together to the search for these two suspects. >> and we were very hesitant to do so because everyone is so on edge. and then they led officers on a wild chase in a stolen car. right now heavily armed police have swarmed a section of watertown.

they're guns are drawn. they've recovered a car possibly connected to the bombing suspect. all boston area schools are closed, businesses are closed, public transportation shut down. everyone told to stay in their homes as officers go door-to-door in a massive manhunt unlike we've ever seen before in this country. >> doing this out of an abundance of caution. one m.i.t. security guard has been killed. they don't want anymore people hurt or killed in the process. >> the fbi are also trying to question people as they minute by minute learning more who's involved. these two brothers had two sisters. one of them lived in west new york. it's a town actually in the state of new jersey. and our maggie lake is there. maggie. >> erin, that's right. what you're looking at is the front door of the apartment building where the sister lives. this has been corp done ecordon

police tape. we just saw a car pull up. there's more movement than we've seen in quite some time, so it may be that either she is about to exit with her husband, possibly. or they're about to start bringing evidence out. one presumes they've been trying to find out if there's been any contact, when the last time she spoke to her brothers. we haven't been able to get a lot of information from law enforcement officials here. they have been on the scene all morning. there is a huge amount of media surrounding this as you can imagine as well as neighbors who are as surprised to see the police here as anyone. not a lot of them seem to know a lot about the sister. we may find out more in coming days. but, again, the sister and her husband we believe inside being questioned by the fbi for more than -- or about two hours now. we have seen some movement. we do think that they might be coming out shortly, erin. >> and, maggie, you know we've heard from the uncle of the nephews. wolf and i were listening when he gave an impromptu press

conference there and talking about the shame he felt of being linked to this. he referred to the brothers as losers, said he had no indication of them being radicalized. but also had no idea that this could have happened and was shocked and dismayed. do you have any sense as to the fbi's belief as to whether the sisters were closer to their brothers in any way than perhaps the uncle? that they might have known more? >> you know, erin, we don't right now. there are some reports kicking around, but i have to tell you there hasn't been a lot of access. they were not answering their door this morning. maybe made a couple muffled comments through the door. they did seem to be in shock and very upset by this, as you can imagine. but again, the reason the investigators have probably been in there for as long as they have is try to determine exactly what sort of relationship they had. they do live, as you said down here in new jersey. there are also reports that there may be another sister in

the area. again, it's so fluid a lot of people are chasing these leads. the investigators certainly on the scene here. they've been in there for a long time. one has to expect they're also trying to -- we expect maybe come out with some materials, perhaps computers as is often the case in this to see whether there has been in correspondence in terms of that. we don't know exactly what the relationship was with this sister, erin. >> thank you. >> we're going to stay on top of that, maggie lake reporting from west new york which happens to be in new jersey. we're going to get back to the investigation, the manhunt underway now for one of the surviving brothers, the younger brother, the 19-year-old dzhokhar tsarnaev. but an update in west, texas. martin savidge is standing by at the fertilizer plant that exploded and kill and injured a lot of people. new information on that. martin, what are you learning? >> wolf, we're getting a couple updates.

first of all they say now the official death toll so far is 12. this is the first time they've given us a real hard figure. so far 12 victims have been recovered from the rubble vultd of that huge explosion that occurred late on wednesday night. also they are saying this they have searched now and the search and rescue mission should be pointed out is still ongoing which of course leads some to believe that there is some hope perhaps more survivors could be found in the rubble. they have now cleared 150e buildings in the area of blast site. they have 24 or 25 more structures to be cleared today. they hope to be done with that before the day is done. and they also say that there are about 50 buildings that have been destroyed as a result of the blast. we just had a briefing from the political representation i could say, the two senators that represent texas, and it was john cornyn who raised eyebrows when he said there are 60 people still unaccounted for. 6-0. and that's of course a number that has many people worried because as time goes by if it's still that high, you have to worry that the death toll could

climb higher. afterwards when we questioned him spervegly he cautioned a bit saying they are double checking on that. take that with a grain of salt. they have to cross check with hospitals, relatives, with addresses to make sure people who said they lived where they did actually did. so it is still very much a search and rescue operation that is underway. they fear the death toll is going to rise. the number of injured now stands at 200, wolf. >> martin savidge on the scene for us in west, texas, with the latest on that fertilizer explosion. the casualty numbers continuing to go up. what is encouraging though, they still think it's a search and rescue operation. they're hoping that they can find some people who may still be alive. >> right. when you hear the discrepancy between 60 still supposedly unaccounted for and the death toll being significantly lower at 12, you have to hope and pray that those people end up, some of them, being found alive. wolf, we just got this tweet that i wanted to share with everyone about what's going on here in boston from the boston

police. they're saying that 60% of the search is done. they're saying that. >> in the watertown area? >> they're saying boston police here's the tweet 60% of the search is done but there's still more work to be done. boston police department referring to the massachusetts police department. again, that's just a tweet. >> which suggests this lockdown in the city asking everyone to stay put, don't use public transportation, don't go to school, don't go to that situation. you know what, we're getting live pictures coming in now. this is the home of the uncle of these two suspects. the uncle's name ruslan tsarni. he probably shortened it from the russian original tsarnaev, probably shortened to tsarni. there you see the uncle walking outside the home. i don't know if that uncle's going to come to the microphone, speak out. as you know, erin, he did speak out extensively a couple hours or so ago and made a very passionate statement

disassociating himself, his family, chechnya, if you will, from these two young boys. and let's play a little bit of that. here's the uncle. his name is ruslan tsarni. and he says these two young men, these suspects one of whom is now dead, brought shame to the family and to the people of chechnya. >> what happened and what we heard this morning about people associated with my family, my family associated, i want to start and i will finish. first, the only purpose here to shed our condolences with those who have been murdered, those who've been injured, this boy,

this chinese girl, this young 29 years old girl, i just been following this. i've been following it from day one, but never ever would imagine that somehow the children of my brother would be associated with that. so it is a shock. we're shocked. again, i don't know this family does not know how to share the grief -- i don't know. we've not been in touch with that family for number of years. for number of years. pardon me? no, they never lived here. they never lived here. >> when is the last time you saw them? >> the last time i saw them was

2006 -- i'm sorry. >> all right. we're going to just interrupt this now. this is the uncle of course of the two suspects. there's a press conference going on now. >> -- shelter in place in work sites and offices throughout the region and particularly in some of our large boston employers. so i need to speak to those people. if you are at work, we do not expect you to shelter in place and stay there. we encourage you to leave to get in your cars and drive home. we understand that public transit is not running. taxis are now running in the city of boston. the taxis are available. if necessary, you can call friends and ask them to pick you up. but we want to make clear that we are not expecting people to be sheltering in place

throughout the day and into the night in businesses. again, i thank the media for helping us deliver this message. we'll push it out a number of ways. again, if you are at work, please feel free to get in your cars and drive home and shelter in place at home. call taxis, if necessary call friends to come get you. thank you very much. schwartz. thank you. there's been no change in the geographic k geographical area covered by our request. we're asking people in the same areas to stay home and stay indoors. thank you.

>> that was kurt schwartz. people still to stay at home. and if you're not at home, get in your car now and go home. >> yeah. they want as few people out on the streets as possible right now because they don't know where the second suspect is. he's 19 years old. named dzhokhar tsarnaev. the younger brother of tamerlan tsarnaev, he's dead. these are the two suspects identified by the fbi in the video and still photos that were released yesterday. massive manhunt underway right now for this younger 19-year-old. he was a student at the university of massachusetts dartmouth. no relation to dartmouth college. university of massachusetts dartmouth here in massachusetts. he's been speaking to a lot of his associates, friends, he was a wrestler on the wrestling team. he seemed to be a normal kid and all of a sudden we're learning maybe not so normal. >> wolf, i had kept a list as we

were interviewing people who knew the younger brother. the older brother, there have not been any people we've been speaking to. the older brother seems to be more reclusive. the younger brother, we've heard again and again positive things about this young man. and yet he has done a who ahorr thing. what changed and how did this happen? we'll take a quick break and be back in just a moment. 800-345-20 tdd#: 1-800-345-2550 and the streetsmart edge trading platform from charles schwab... tdd#: 1-800-345-2550 gives me tools that help me find opportunities more easily. tdd#: 1-800-345-2550 i can even access it from the cloud and trade on any computer. tdd#: 1-800-345-2550 and with schwab mobile, tdd#: 1-800-345-2550 i can focus on trading anyplace, anytime. tdd#: 1-800-345-2550 until i choose to focus on something else. tdd#: 1-800-345-2550 all this with no trade minimums. tdd#: 1-800-345-2550 and only $8.95 a trade. tdd#: 1-800-345-2550 open an account with a $50,000 deposit, tdd#: 1-800-345-2550 and get 6 months commission-free trades. tdd#: 1-800-345-2550 call 1-866-564-1336. plays a key role throughout our lives. one a day women's 50+ is a complete multivitamin

now. their uncle, a man of ruslan tsarni, he walked out of his house. we didn't know what he was doing, but he actually wanted to go and you can see he went to the neighbors to basically apologize because all the media have located outside of his house. he made a bit of a passionate statement to the media a while ago to completely try to disassociate himself, his family, people of chechnya from these two young men. >> talk about the shame that he felt. i also wanted to report something here, wolf. we have reported that dzhokhar, the younger son, got his citizenship on september of 2012. the younger suspect at large right now got his citizenship on september 11th. so we called the u.s. citizenship and immigration services can you choose your day? we were wondering, they

confirmed indeed that you cannot. >> what a coincidence? 19-year-old dzhokhar, the man being searched by local, state and national authorities got his u.s. national citizenship come here with asylum, got a green card and came to the united states. >> yes, on september 11th, which is an irony. as we try to put this together and take things like that and place them in what eventually right now everything is a rubic's cube. this young man essentially went from being a normal kid, very successful in a lot of ways with promise, had won a scholarship at cambridge for $2,500 when he was a senior in high school. how he became a killer. how he became someone who could do something so horrible. that chronology will come together of how that happened so rapidly. >> let's go to tom fuentes right now.

he's the former assistant director of the fbi, our cnn law enforcement analyst who's really been helping us better appreciate what's going on behind the scenes. we know there's a lot going on here in the boston area in cambridge where these two suspects lived, in watertown where the encounter with the older brother ended last night in his death and the killing of this m.i.t. police officer -- what's going on? washington right now? how much coordination, tom, is there from the federal government in washington and whether the justice department or other agencies in the u.s. government? >> well, wolf and erin, there would be general oversight from washington. obviously at fbi headquarters and department of justice, but much of the focus and much of the coordination is really on site in boston among all of the agencies that are part of this massive investigation. so really the main coordination is actually occurring in boston with oversight from washington.

and then also you have the tactical oversight or the tactical or incident command post would be very close to where these searches are going on right now. but i'd like to add something else that would be going on in washington, at quantico and in boston is that fbi and police psychologists would be working from the beginning to try to analyze these two, look at their demeanor in the videos, the interview of family and friends and classmates to look at their psychology. and i'm not hearing this officially, but it seems to me from the videos that -- and from what we've been hearing from some of the interviews done in the media today that the older brother was the leader of the two and that the younger brother seems to have been a congenial great american kid, an athlete and leader and sociable and all of that. and somewhere in the dynamic it appears that the older brother brings him along to follow his

idea of what's going to happen. in the videos you see the little brother tagging along two or three feet behind him and following him up and down the sidewalk. so what i'm getting at is that since that brother is dead since last night, now what's the psychology of the little brother who was tagging along doing what the big brother wanted, now he's on his own. and you're hearing if he's watching media coverage and seeing family members disavow and say they're ashamed of him and calling him a loser, the big brother is dead. you know, rapidly the support group that he may have had even if it was a one, his brother, is gone. so now how does he think? as he becomes a cornered animal and especially as the police are sweeping these apartments and getting closer and closer to him, now what's he going to do? i think that's the concern right now is that he's going to be as dangerous as possible at this point. and he may want to go ahead and

really make a blaze of glory if he can using explosives, firearms, whatever means. they've already killed -- or he already killed a police officer last night. nothing's going to stop him from doing that again. he's got nothing to lose. they killed so many people, they committed this horrible act, now he's on his own. so he's committed this horrible act. i think that's going to play a large part of what happens in the hours to come here. what is he thinking? that's something of major concern to the authorities now. >> yeah, you have to assume not only is he armed and very, very dangerous as the fbi has been saying, this 19-year-old dzhokhar tsarnaev, but also maybe wearing an explosive vest designed to kill a lot of people in the process and take himself out in a suicide, erin, in the process. >> and that is the terrifying fear that they have. wolf, we have a little bit of new information i want to share that we've been able to confirm. and that is that dzhokhar came to the united states when he was 8 years old. >> this is the younger brother.

>> the younger brother, the one currently still at large came on a tourist visa and eventually became a naturalized u.s. citizen in september of last year. so he was 8 years old, a few days shy of his ninth birthday. his brother though from the sort of profile experts have been showing seems to have been the leader or master mind. >> he was 26 and obviously a 26-year-old is going to be more mature than a 19-year-old. >> and we don't know the relationship between the two, but sometimes and idolize or look up to your older brother. the brother didn't come to the united states, tamerlan until he was killed last night in 20 years old. gives you the most informative experiences in his life were, whatever inspirations he had for the person he became, that happened somewhere else. >> and applied for asylum and permission to stay in the united states arguing if he were to go back to kyrgyzstan or chechnya or some place like that, the former soviet union, one of those republics, predominantly muslim areas, he could be in

danger. >> that's what he said. they were both here legally. the younger one a naturalized u.s. citizen and the older on a green card, but again legally here. >> you know, i think we want to talk a little about the controlled explosions that are about to happen. mike brooks, the hln law enforcement analyst is joining us right now. you know a lot about these controlled explosions. they can be pretty terrifying if you're in a neighborhood, mike, and you hear a loud boom and you don't know this is something that law enforcement is deliberately doing, you could be pretty scared. >> oh, absolutely, wolf. i'm glad that the colonel from the massachusetts state police let everyone know that this would be happening. you know, this is -- they're concentrating right now on norfolk street there in cambridge where the two brothers apparently lived in this apartment. but we don't know if there's explosives in the apartment. what they're doing right now, special agent bomb techs from the field division and also i can guarantee you there's explosive examiners from

quantico, from the explosives lab in quantico, virginia. what they want to do is make sure they can gather as much evidence as possible in this apartment where they live. so, you know, they're doing an assessment. they probably have already done an assessment and decided what they're going to do. have they looked inside and seen something they didn't like? if you recall back at aurora, colorado, where james holmes was, wolf, you know we saw them using an alternate breach site. we saw them break a window and break in. they saw something they didn't like and then decided to do a controlled explosion or we would call it a render safe procedure using a disrupter. so this is probably what's going on there at the apartment in cambridge, wolf. so what they'll do is when they get ready they'll probably let people know and you'll hear fire in the hole, fire in the hole, fire in the hole and then you'll hear a boom. now, could it be to disrupt something that they see there already? that's a possibility. or could be to get into the apartment.

and if there's something there, you could also hear another boom after that that could be a sympathetic detonation inside of something they're trying to disrupt. we don't know exactly what they have inside that apartment, but again out of abundance of caution, the special agent bomb techs as well as members of the fbi's evidence response team there to pick up and do a small post-blast there, they're trying to gather as much evidence as they can. but again, being safe is possible. and we've also seen the cambridge fire department outside with one of their trucks hooked up to a fire hydrant for a water supply just in case there's any kind of thermal event, any kind of fire when this takes place. but again, they are doing everything, wolf, out of abundance of caution. >> standby for a moment, mike. we have a guest. mike sullivan is here with us, the former assistant director of the bureau of alcohol, tobacco and firearms. thanks so much for coming in. we hear a lot about these controlled explosions. would they actually explode one of these devices inside an

apartment in cambridge? >> they'll do it make sure that the public is protected from the safety perspective as well as the bomb techs as well. this is a judgment that they have to make on a case by case analysis between deactivating a device in order to control the explosion. the controlled explosion really is intended to protect people. they'll do it in a way that provides great protection. >> will they mother that bomb first? you could blow up a whole building if you're not careful. >> obviously they're experts with regard to this type of area. bomb techs have been doing this type of work for decades. they have a wealth of experience. they have to make some judgment calls as to which the most safest way of handling that explosive material. >> but it's pretty incredible that they can do that. when you think about the skills that they have and the ability they have to deal with the situation, that they can do it as wolf said in an apartment building. >> well, they are. and in some instances they essentially deactivate the device themselves. but they'll do it in a way that's going to protect obviously the technicians and

protect the other public. so they'll make sure that they're prepared in the event something else happens. >> don't go too far away. we are going to continue this analysis. we're awaiting, erin, controlled explosion because the suspicion is these two suspects had a lot of explosive devices in the cambridge area. >> that's part of what they have been doing in the door to door search, looking for a person and also looking for devices. we're going to take a very quick break. we'll be right back. humans. even when we cross our "ts" and dot our "i's", we still run into problems. that's why liberty mutual insurance offers accident forgiveness with our auto policies. if you qualify, your rates won't go up due to your first accident. because making mistakes is only human, and so are we. we also offer new car replacement, so if you total your new car, we'll give you the money for a new one. call liberty mutual insurance at...

we're continuing our nonstop coverage of the manhunt under way here in the boston area, a manhunt for a 19-year-old, dzhokhar tsarnaev, the younger brothers, one of the two suspects who believed allegedly was responsible for the bombings at the end of the boston

marathon. >> he took credit for that last night with a man that they hijacked him in his car. >> and then let that man go. >> they let that man go. which is another very interesting small part of this story. fascinating. >> mike sullivan with us, former acting director of atf, he's here in boston with us. it is pretty weird, and i know you're an expert on these kinds of areas. they go ahead and kill an m.i.t. police officer, they wound another one, they hijack a car. and then they let the driver go after telling the driver we were responsible for the bombings at the boston marathon. >> real no rhyme or reason with regard to the way that they just kill innocent people, maybe that was their way of getting their message out that they were responsible for the bombings. >> these bombs were described, i mean, they killed three people, the boston marathon, they injured almost 200 as supposedly two bombs crude and pressure cooker, if you will, is that a

fair description? you're a former head of the atf. >> crude to the extent there was nothing sophisticated about the bombs. pressure cooker bombs. in fact, a lot like pipe bombs except using a pressure cooker, packed with low grade explosive material, having some type of detonating device. something that can initiate the spark that low grade material, build up the gases and then cause the explosion. >> we have been talking a lot about the contradiction between last night's behavior and today, where they seem completely discombobulated and out of control, had no money, hijacked a car and how organized and planned they must have have been in the attack itself. do you think they were planned and they knew they were on video, all these things we assumed yesterday, or is it possible they were so confident with their ideology that -- >> you know, likely the latter. obviously the planning of the bombing was pretty significant. >> hold on one second. >> sorry to interrupt. >> we're -- i guess we're going to go to deb feyerick, is that

right? >> tamerlan is -- >> t is the aunt. >> smart boy. seemingly did not find himself yet in america, because it is not easy. my younger brother ruslan, he had high expectation of him. because he knew he was smart. he knew he could use his potential, but, you know, and then when he found out that he dropped out of university, that was ruslan was desperate because he always demands more of his children, of his nephews, especially tamerlan, his favorite, so as i said, he's smart guy. >> can you tell us about when they came to the united states, where they had been living before that?

>> i brought them here. i was in the states, going through my paperwork. >> when was that? >> that was 2001. so then in 2002 my older brother came to the states, that's when i find out his paperwork, myself, for the refugee protection claim. >> your older brother -- >> older brother. no. then in april of 2002, boy's father, his wife and little dzhokhar, came to the states. that's when i filed a petition for their refugee status. because back home he worked as -- he worked in the enforcement agencies. he also -- he was prosecuted. we were lucky to take him out of

kyrgyzstan alive. that's when they came. april 2002. >> did you ever talk to them about living in america? did they like it? what did they tell you? >> they always like it, you know. they liked it, they lived there. they didn't like it, they would leave. >> did they tell you anything about their life in boston? >> kids' lives, freedom, that's what it is. kids, as soon as they know, they are free, they do whatever they want, they don't listen to their parents, especially when they grow up. so that's it. i didn't say he was struggling. i said it seemed like he wanted to find out what he wants. but at that age, all they want is love. so he found his love. he marries, he had a daughter and he was happy about his daughter. >> which one are you talking about? >> older one. >> tamerlan. >> they moved to canada first and then to boston. >> i didn't say he came to

canada first, guys, listen. they came to the states. to the states. in 2002. first parents came. mother and father and dzhokhar, when he was little. three kids were back home in kazakhstan living with my younger brother. so they came first. because he never goes anywhere with his wife. so that's why they came here, fled -- we applied for refugee stat ous in the states. and he was given that status. and, by the way, likely -- it was given lightly because he founded, you know, he was convincing. so got his refugee status. and few months his kids united with them. >> you said he never traveled with his wife. tell us about the family -- >> without wife. >> pardon me. tell me more about --

>> without wife. because he loves her dearly. >> tell us more about the family. what was the home situation like for the boys? >> growing up, within a family, everything was perfect. because he is a warm loving whole hearted father. i don't know what will happen to him now when he hears this. but apparently, even when i hear, like, you know he said this and that, i don't believe ansor said that. who that said is his wife. i don't believe that ansor is even able to speak now. as much as i know my brother, he would not be able to speak over the phone hearing this news. >> where is he now? >> he's in -- his wife is there also. she joined him a few months ago because they were going back and forth and back. i mean, his wife was going back and storage because they
